NATIONAL TRANSPORTATION SAFETY BOARD Office of Research and Engineering Vehicle Recorder Division Washington, D.C. 20594 GROUP CHAIRMAN’S FACTUAL REPORT OF INVESTIGATIONDCA13MA120 By Joe Gregor WARNINGThe reader of this report is cautioned that the transcription of a cockpit voice recorder audio recording is not a precise science but is the best product possible from a Safety Board group inv estigative effort. The transcript or parts thereof, if taken out of context, could be mi sleading. The transcript should be viewed as an accident investigation tool to be used in conjunction with other evidence gathered during the investigation. Conclusions or interpretations should not be ma de using t he transcript as the sole source of information.

On July 6, 2013 at 1128 am local time, a Boeing 777, registration HL7742,operated by Asiana Airlines as flight 214, struck the seawall short of runway 28L at SanFrancisco International Airport. The airplane was destroyed by impact forces and fire.Three of the 291 passengers were fatally injured and about 199 were transported to thehospital with injuries. One of the 4 flight crew and 10 of the 12 cabin crewmembers wereinjured. The flight was a regularly scheduled passenger flight from Incheon International
Airport, Seoul, Korea, and was operated under the provisions of 14 Code of FederalRegulations Part 129. Visual meteorological conditions prevailed at the time of theaccident.
D. DETAILS OF INVESTIGATION
On July 7, 2013 the NTSB Vehicle Recorder Division’s Audio Laboratory receivedthe following CVR:
Recorder Manufacturer/Model: Honeywell 6022 (980-6022-001) Recorder Serial Number: CVR120-07983
Recorder DescriptionThis model CVR is a solid-state CVR that records 2 hours of 2-channel digital
cockpit audio, and 30 minutes of 3-channel digital cockpit audio. The recorded audiodata is separated by the download software into 5 separate audio data files. The
recording consists of one 2-hour long channel that contains audio information from thecockpit area microphone (CAM), one 2-hour long channel that contains audioinformation summed from all of the individual crew positions (HOT), and three 30-minute long channels that contain audio information from each of the individual flight
Timing and CorrelationTiming on the transcript was established by correlating the CVR events to common
events on Flight Data Recorder (FDR). Specifically, multiple data points related to radio
microphone keying events recorded on both the CVR and the FDR were used. Eachpoint acted as an anchor point for a linear interpolation between the remaining CVRevents. The correlation resulted in agreement between the two recordings within ± 0.2second. Times listed in the transcript portion of this report are given with 1/10 secondprecision, and are based on visual identification of the beginning of the waveform foreach phrase as displayed by the NTSB transcription software. Reported PDT time isaccurate to ± 1 second, based on correlation between the CVR recording and time datarecorded on the FDR.
Description of Audio EventsThe recording began at 0922:29 PDT, with the CVR recording sounds consistent
with the aircraft in cruise flight. At approximately 0934:47 PDT, the pilots noted that theglide slope would not be available and discussed routine operational issues concerningthe flight, approach, and landing. At approximately 0955:45 PDT, the pilot flying (PF) theapproach into San Francisco entered the cockpit and the crew discussed routineoperational issues concerning the flight, approach, and landing. At approximately0955:45 PDT, there was a transfer of aircraft control to the PF. Approximately 6 minuteslater, the crew discussed expectations for receiving radar vectors for a visual approach.
At approximately 1033:51 PDT, the flight contacted Center and reported at FL390. Atapproximately 1038:50 PDT, the PF excused himself from the cockpit. At approximately1040:19 PDT, the flight was given clearance to San Francisco using the Golden Gate 6arrival via Point Reyes. At approximately 1040:41 PDT, the PF returned to the cockpitand resumed aircraft control.
The remainder of the CVR recording, starting at time 1042:27.8 PDT, wastranscribed as shown starting on page 12-8. The recording ended at 1128:02 PDT.
The levels of recording quality are characterized by the following traits of the cockpit voice recorder
information:
Excellent Quality Virtually all of the crew conversations could be accurately and easily understood.The transcript that was developed may indicate only one or two words that werenot intelligible. Any loss in the transcript is usually attributed to simultaneouscockpit/radio transmissions that obscure each other.
Good Quality Most of the crew conversations could be accurately and easily understood. Thetranscript that was developed may indicate several words or phrases that werenot intelligible. Any loss in the transcript can be attributed to minor technicaldeficiencies or momentary dropouts in the recording system or to a large numberof simultaneous cockpit/radio transmissions that obscure each other.
Fair Quality The majority of the crew conversations were intelligible. The transcript that wasdeveloped may indicate passages where conversations were unintelligible or
fragmented. This type of recording is usually caused by cockpit noise thatobscures portions of the voice signals or by a minor electrical or mechanicalfailure of the CVR system that distorts or obscures the audio information.
Poor Quality Extraordinary means had to be used to make some of the crew conversationsintelligible. The transcript that was developed may indicate fragmented phrasesand conversations and may indicate extensive passages where conversationswere missing or unintelligible. This type of recording is usually caused by a
combination of a high cockpit noise level with a low voice signal (poor signal-to-noise ratio) or by a mechanical or electrical failure of the CVR system thatseverely distorts or obscures the audio information.

receive clearance from ramp tower. through number two, wego Alpha five. usually we are given Alpha five.}

10:49:21.1CAM-1 {I understand that people, who have many outdoor activities,
are recommended to wear them to protect eyes. But I can'twear sunglasses. I usually use them while in cruise flight, butalways take them off when on approach.}
10:49:40.8CAM-2 {I even take them off to focus when on approach.}10:49:44.3CAM-1 {approaching with wearing sunglasses when I flew seven six

working under scorching sun without any problems withoutwearing sunglasses, and can read up to that old age.}

who is sophomore in high school has bad eye sight 0.5.}10:51:14.4CAM-1 {my son had third grade of eye sight testing in physical.}
10:51:21.8CAM-2 {oh, can you get third grade because of eye sight?}10:51:25.6CAM-1 {yeah, not exempted unless it is 0.01 like really bad.}10:51:27.4CAM-2 {yeah.}10:51:33.6CAM-1 {and lately there will be no exemption with only one item,
especially bad eye sight, can't make it happen because eyeglasses and so on are available.}
10:51:38.9CAM-2 {aha.}10:52:06.6CAM-1 {I don't know whether my son should do Lasik or * *. some
recommend to perform and some not. But my nephew, whohad really bad eye sight, just did it and he said his life stylehas been changed since.}
10:52:23.6CAM-2 {it really depends on how skilfully the doctor corrects the
cornea; I mean how the doctor deals with the thickness of it.But it seems they are not operating well. That may be thereason pilots complained after the correction.}
10:52:43.2
CAM-2 {I know it corrects the sight, but there's some risk also. and Iwas told that Lasik is not recommended to those who havehin corneas.}
10:52:52.0CAM-1 {humm.}10:52:54.2CAM-2 {captain @ who moved to Air Busan had a blocked artery,
has high eye pressure always because his cornea is 1.5hicker than average people.}
10:53:06.9CAM-1 {aha.}
10:53:07.5CAM-2 {whenever his physical performed, his eye pressure is alwayshigh.}
10:53:15.5CAM-1 {I see captain @ is in Air Busan.}10:53:19.6CAM-2 {yeah, he is a manager in safety management team in Air
10:55:26.1CAM-1 {so the benefit is dramatically diminished. But we still can use
